ELECTRICAL CHARACTERISTICS
MOTOROLA
TECHNICAL DATA
A-11
NOTES:
1. For fop < 2 MHz, source impedances should equal approximately 10 k. For fop ≥ 2 MHz, source impedances
should equal approximately 5 k
– 10 k. Source impedances greater than 10 k affect accuracy adversely be-
cause of input leakage.
2. Performance verified down to 2.5 V
V
R, but accuracy is tested and guaranteed at VR = 5 V ± 10%
